Issues of Reliability and Validity of Data - Assignment Example One can take both types of data, primary as well as secondary, for the consumers’ demand in these countries. Both the types of data are necessary for finding out the consumer demand in a country. Primary data will provide the information which has not been collected before as it is collected as per the need of the research. Usually the process is expensive and time consuming.

Qualitative as well as quantitative data are very important for analysis and ensuring the validity and reliability of the consumer behavior data. Quantitative data are more reliable and valid than the qualitative data. T he method for establishing the validity and reliability of qualitative data takes the form of expert interview, participant feedback, regression analysis, and statistical analysis.
